Diagnostics reveals code 52 knock sensor..........our online manual says
ck for bad sensor, wiring or ECU.
A) where is the sensor on a 86mkII 5mge?
B)how can i test it?
c)how can i tell if the ECU is at fault?????

Now i don't know when the last tune up was but the car runs good other than a little stutter when you gas On it from idle.

This sensor does'nt actually sense rod knocks or piston slap does it?????
that would be the first time i ever heard that lol.

ok gang, which road down the mechanical hwy to i take first???????

Thanks,

Its located on the engine block under the intake manifold on #3 cylinder. Common that the one wire to it might have become disconnected. Its a piezzo microphone that detects pinging in a certain frequency only that would likely indicate preignition. The ECU retards timing to compensate. Not sure if TSRM has way to check besides just the code, its not in front of me, but I would just swap in another from a salvage yard and see, that is if its not the wire. In the meantime, set timing to 10 degrees and run 89 or higher octane and you will be fine.
